To all'who'm it may concern: y

NICHOLS, of East Haddam, in the county of Middlesex andfbt'ate of Connecticut, have' madeV aninvention of vcertain new and useful Improvements 'in Ring-Spinning Frames; and

that the following is a full, clear,and exact description and specification ofthe same.

The object of this invention isfto-euable the spindles of ring-spinning frames to'- be constructed of light weight' and to be driven at afhigh speed, it being well understood among spinners that the less the'weightof spindles the faster they canA be driven, and alsothat the power required to drive spindles' of different weights at equal speedsdiminishesas the spindles are less in weight.

To this end my invention consists ofcertain combinations of' the bobbiny orcop-tube, the spindle-bobbin, and spindle-bearings,- whereby the spindle is relieved from a large portion of the strain incident to supporting the bobbin, while the latter is supported at its lower end independently of the spindle by a revolving or live box, which runs upon a fixed support, and which has motion imparted to it by the bobbin itself.

The several combinations of devices which constitute my invention are set forth at the close of this specification. In order that they may be fully understood, I have represented in the accompanying drawing, and will proceed to describe, a portion of a ring-spinning frame embodying my invention in the best form thus far devised by me, it being understood that the other parts of the ring-spinning frame are the same as those in general use.

Figure l represents a cross-section of the bolster-railJ with one spindle and its appurtenances in elevation. Fig. 2 represents a vertical central section through the spindle.

rI he spindle A, represented in the said drawing, is stepped at its lower end in a bracketbearing or step, B, and it is maintained in its upright position by the xed tubular bolster C, the bore of whose upper end d forms the fixed upper bearing ofthe spindle. The spindle is thus supported at vits two ends, and is free of any strain between its two bearings other than that due to the whirl E and the driving-band applied thereto.

The pointf of the spindle projects slightly` above it`s`-xed bearing-,and is forked to forml 'a driving-head for the bobbin G, which isv fitted with a-crossLbar, e, toeng'age with'said ,driving-head, -f I The bobbin is lttedat its upper end tothe driving-head ofthe spindle, and is-bored out so as to pass freely over the fixed tubular bol`h ster without touching its surface.v

The lower end of the bobbin iitsupon a shortllive box or' revolving bea-ring, g, which may be of metal or other suitable material,

and is iitted to revolve upon the exterior-of the iixed bolster C, near the bolster-rail H.

rIhis live box or tube transmits to this ixedl bolster any lateral strains that vmay befap.-r pliedtothe lower end ofthe bobbin', which is'thusA firmly supported independently of the spindle, while the-box1v or live-tube which runs upon'lthis fixed-bolster, being'of short" length, is connected with the spindle only through the intervention of the bobbin, and is thus driven by the bobbin itself.

In order that the bobbin may be readily connected with the short live tube or box g without risk of slipping thereon, and may be readily disengaged, the live box or tube g is fitted at its exterior with an elastic sleeve o1 cushion, l, which may be of vulcanized rubber or other suitable material; and in order that the live tube or box g may not be withdrawn from the fixed bolster G when the bobbin is removed, a collar, h, is driven upon the said fixed bolster C, above the live tube g. In order that the upper end of the bobbin may be always centered'upon the spindle A, the bobbin is fitted with a narrow internal ringbearing, s, made of metal or other material that is not affected by atmospheric variations as wood is. This upper ring-bearing, being narrow, does not bind the bobbin longitudinally to the spindle; consequently the bobbin is free to adjust itself to its two supports, which are the point d of the spindle and the live tube g, which runs upon the fixed bolster G.

'Ihe above-described system of constructing spindles and bobbins andtheir respective bearings furnishes a firm and reliable support for each end of the bobbin. As the support of the upper end of the bobbin is the point of the spindle, close to the tubular bear-l ing thereof, there is much less tendency to cause the spindle to tremble or vibrate than there is when the spindle is constructed to protrude sufficiently above its upper bearing to sustain the bobbin wholly. 0n the `other hand, the support of the lower end of the bobbin is independent of the spindle, thus relieving the latter of a great portion ofthe lateral strain. The employment of the narrow internal bearing or box s, at the upper end of the bobbin, relieves the spinning mechanism from the cramping and binding of the head of the bobbin upon the spindle that would ensue from variations that occur in the heads of wood bobbins from atmospheric changes. The cross-bar e, or some equivalent therefor, at the upper end of the bobbin, forms a positive connection between the drivinghead of the spindle and the bobbin, which,

while compelling the bobbin to revolve with the spindle, permits the bobbin to hang loosely on the spindle-head, so that the box at the lower end of the bobbin can adapt itself to the' tubular bolster without pressing unduly at one side thereon. The short live tube g, for the lower end of the bobbin, relieves the spinning mechanism of the cramping and binding of the bobbin upon its fixed bolster that would ensue from variations in the lower ends of wood bobbins from atmospheric changes. The elastic sleeve l prevents all chatteringbetween the lower end of the bobbin and its live tube or box, and adjusts the live tube or box to small variations in the bores of different bobbins. The driving of the live box g by the bobbin itself simplifies the mechanism by dispensing with any other connection between that box and the driving mechanism of the spinning-frame.

I claim as my invention- 1. The combination, substantially as before set forth, of the spindle having a driving-head at the upper end to carry and drive the bobbin, the iixed tubular bolster, and the short live box or bearing for the lower end of the bobbin, constructed to revolve upon the exterior of said bolster near the bolster-rail.

2. The combination, substantially as before set forth, of the spindle, the fixed bolster, the short live box for the lower end of the bobbin, constructed to revolve upon the exterior of said bolster near the bolster-rail, and the elastic sleeve for the said short live box.

3. The combination, substantially as before `set forth, of the spindle having a drivinghead for the bobbin, the fixed bolster, the

short live box for the lower end of the bobbin, constructed to revolve upon the exterior of said bolster near the bolster-rail, and the bobbin fitted at its upper end with a cross-bar that engages with the driving-head of the said spindle.
